.PD
Fix all partialities at 1.
.IP \fBoffset\fR
.PD
Treat the radiation as perfectly monochromatic, and calculate the partiality as exp(-t^2/R^2), where t is the excitation error and R is the reflection radius (taking mosaicity into account). This model is similar to that used by XDS.
.IP \fBggpm\fR
.PD
An analytical overlap integral modelling the reflection profiles as Gaussian functions, and the radiation spectrum as a sum of Gaussians.
